Radio astronomy has changed. For years it studied relatively rare sources, which emit
mostly non-thermal radiation across the entire electromagnetic spectrum, ie radio quasars …

▪ Abstract Deep surveys of the cosmic X-ray background are reviewed in the context of
observational progress enabled by the Chandra X-Ray Observatory and the X-Ray Multi …

The XMM-Newton Observatory is a cornerstone mission of the European Space Agency's
Horizon 2000 programme, and is the largest scientific satellite it has launched to date. This …

We present an evolutionary model for starbursts, quasars, and spheroidal galaxies in which
mergers between gas-rich galaxies drive nuclear inflows of gas, producing starbursts and …

We perform a comprehensive study of the X-ray emission from 70 transient sources that
have been classified as tidal disruption events (TDEs) in the literature. We explore the …

We present the source associations, cross-identifications, and multi-wavelength properties
of the faint radio source population detected in the deep tier of the LOFAR Two Metre Sky …

We present the most up to date X-ray luminosity function (XLF) and absorption function of
active galactic nuclei (AGNs) over the redshift range from 0 to 5, utilizing the largest, highly …

We investigate the cosmological evolution of the hard X-ray luminosity function (HXLF) of
active galactic nuclei (AGNs) in the 2–10 keV luminosity range of 10 41.5–10 46.5 ergs s-1 …

We present a detailed and self-consistent modeling of the cosmic X-ray background (XRB)
based on the most up-to-date X-ray luminosity functions (XLF) and evolution of Active …

Aims. We present the second ROSAT all-sky survey source catalogue, hereafter referred to
as the 2RXS catalogue. This is the second publicly released ROSAT catalogue of point-like …
